PROCESS OF MAKING FIBROUS PADS OR BATTING.

$PEGIFIGATION forming part of Letters Patent No. 768,599, dated August 30, 1904. Application filed April 27, 1904. Seria1 No. 205,237 (No specimens.)

To all whom it may concern:

Be it known that I, GUsTAv GOLDMAN, of Baltimore, Maryland, have invented a new and useful Process of Making Fibrous Pads or Batting, which invention is fully set forth in the following specification;

The present invention relates to the art of making pads or batting of fibers or fibrous material, whether of animal, vegetable, or minmat down in a solid mass, which when the sizing is dried is non-resilient and undesirable for use as pads or batting.

In my United States Letters PatentNo. 758,243 I have described a process of binding fibers together by introducing between the fibers dry finely-divided binding material and subsequently treating this binding material so as to convert it into an active binder for the fibers. ting down of the fibers, resulting when a liquid binding material has been employed as heretofore.

The object of the present invention is to employ a liquid binder or a binding material applied in liquid form or solution and at the same time avoid the matting effect, which gives a hard and non-resilient mass of fibers when the binder is dried.

With this object in view the invention consists in treating the fibers with, a suitable liquid binder and subsequently subjecting the fibers to a treatment which will separate them and lay them down in a light fluffy condition with the binding material thereon, after which the fibers are subjected to a drying process, preferably in the presence of slight pressure, whereby the. fibers will be bound together in a light resilient mass suitable for use in gar- In this way I avoid the matment-pads, batting, and the like. Preferably the fibers are divided into a light fluify mass after the liquid sizing has been applied thereto by treatment. in an ordinary cardingengine, and it is therefore desirable that the liquid binder employed should be of such a character as not to unnecessarily gum up'the machinery in a manner to materially interfere with its operation. which I have found to be excellent for this purpose, serving to eff ciently bind the fibers together and at the same time leaving the machinery comparatively free from gumming action is adilute solution of Irish moss, a one per-cent. solution having been found to be efficient for most purposes.

In practicing the process the mass of fibers to be treated may have the liquid binder sprayed thereon or the fibers may be im mersed in a vat and the liquid binder subsequently drained or wrung out in any suitable way, after which the fibers are placed in the bin of the carding-engine and are passed therefrom through the carding-engine and discharged from the doffer of said engine in a light fluify mass.

One efficient means of treatment has been found to cause the 'doffer of the carding-engine to lay the fibers down in this light and fluffy condition upon a traveling belt, which belt is caused, together with the fibers thereon, to. pass between heated rollers. These rollers are provided with means of adjustment toward and from each other to the end that the desired amount of pressure may be applied to the mass of fibers and are heated in any suitable way, as by steam. If desired, the belt itself need not necessarily pass between the rollers, the film or mass of the fibers passing from the belt directly between the rollers. The fibrous mass having thus been subjected to heat and such pressure as is desired to bring it into proper form is then discharged from the rollers and 1s 1n proper condition to be bundled up as batting for ship- 9 ment or forformation into garment-pads, as may be desired. Practical experience has demonstrated that by this method a light fluffy pad or batting may be secured free from the hard non-resilient condition heretofore One of the binders found to exist when fibers have been treated with a liquid binder. Moreover, with the liquid binder, such as the solution of Irish moss mentioned, the carding-engine employed can be operated for a considerable length of time before it is necessary to stop the engine for cleaning.

Having thus described my invention, what I. claim is 1. The process of making fibrous pads or batting, which consists in treating a mass of fibers with a liquid binder, subsequently separating the fibers, and then laying them down in a light flufiy mass or condition, and then drying the fibers.

2. The process of making fibrous pads or batting, which consists in treating a mass of fibers with a liquid binder, then laying the fibers down in a light flufiy mass or condition, and then drying the fibers.

3. The process of making fibrous pads or batting, which consists in treating a mass of fibers with a liquid binder, eliminating any excess of liquid binder from the mass, then laying the fibers down in a light flufi'y mass, and then drying the fibers.

4c. The process of making fibrous pads or batting, which consists in treating a mass of fibers with a liquid binder, then carding the fibers, whereby they are divided into a light fluffy mass, and then drying the fibers.

5. The process of making fibrous pads or batting, which consists in treating the fibers with a liquid binder, then carding the fibers,

whereby they are separated into a light fiufi'y mass, and then subjecting this light fiu fi'y mass to heat and pressure.

6. The process of making fibrous pads or batting, which consists in treating the fibers with a liquid binder, removing excess of liq u'id from the mass, carding the fibers, whereby they are formed into a light fiufi'y mass, and then subjecting the fibers to heat and pressure.

7. The process of making fibrous pads or batting, which consists in treating the fibers With a liquid binder, then carding the fibers, whereby they are converted into a light fiufi'y mass or condition, and sinnlltaneously subjecting said light, fiufiy mass to heat and pressure.

8. The process of making fibrous pads or batting, which consists in subjecting a. mass of fibers to a. solution of Irish moss, then (-ard ing the fibers, whereby they are brought into alightfiufi'y mass or condition, and then passing the fiufi'y mass of fibers between heated rollers.

in testimony whereof I have signed this specification in the presence of two subscribing witnesses.
